充電装置および電動車輌
Document Type and Number:
Japanese Patent JP4134509
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a charger which is simple for a secondary battery. SOLUTION: A capacitor C1 is disposed on the input side of an inverter and connected to a power supply for charging through a diode bridge D1. When charging, the junction of the star-connection of a three-phase motor 50 and one side of terminals of a battery 20 are connected. With this condition, switching elements on the power supply side of the inverter are switched on/off, an electric charge which the power supply is rectified by the diode bridge D1 and accumulated in the capacitor C1 flows into the battery 20 through the switching elements and each phase coil of the three-phase motor 50, and charges it. Since the diode bridge D1 is used for the charger, both AC power supply such as a commercial AC power supply and DC power supply like a fuel cell can be used as the power supply for charging the charger.
